Three Phases Diode Clamped Inverter Using SVPWM Method for Induction Motor Fed Electric Vehicle Application

Abstract

to improve air quality in heavily populated urban communities have rekindled interest in the development of electric vehicle technology. Solar electric vehicles (SEV) are considered the future vehicles to solve the issues of air pollution, global warming, and the rapid decreases of the petroleum resources facing the current transportation technology. However, SEV are still facing important technical obstacles to overcome. They include batteries energy storage capacity, charging times, efficiency of the solar panels and electrical propulsion systems. In this paper, a hybrid Photovoltaic (PV)-fuel cell generation system employing electrolyze for hydrogen generation is designed and simulated. The system is applicable for remote areas or isolated loads. Fuzzy regression model (FRM) is applied for maximum power point tracking to extract maximum available solar power from PV arrays under variable isolation conditions. The system incorporates a controller designed to achieve permanent power supply to the load via the PV array or the fuel cell, or both according to the power available from the sun. The IM is fed from three phase inverter operated by a constant V/F control method and Space Vector Pulse Width Modulation (SVPWM) algorithm. The electric vehicle is propelled by three phase cage induction motor and powered by batteries which are charged by solar energy station. Due to its low cost, robustness, high reliability and free from maintenance, automobile industry will certainly select cage induction motor as the most appropriate candidate for EVs. Hence, it is believed that the work carried out will contribute in development of future electric vehicles based on the use of squirrel cage induction motor. This concept can be extended by applying Three phase Diode clamped Inverter at source side to apply for Induction Motor fed Electric Vehicles,  i.e, Three phase Diode clamped Inverter Using SVPWM Method for Induction Motor fed Electric Vehicle Application. by using Matlab/Simulink software
